S4220F

Single Diodes Overview

The S4220F is a standard recovery rectifier manufactured by Microchip Technology, designed for high-current applications. It features a single diode configuration housed in a DO-205AA (DO-8) stud mount package. The device supports a maximum repetitive reverse voltage of 200 V and an average forward current of 125 A. It exhibits a typical forward voltage drop of 1.2 V at rated current and can withstand a maximum surge current of 2 kA. The component operates reliably within a junction temperature range of -65 °C to +200 °C.

Single Diodes Procurement Notes

Verify the specific suffix 'F' against the official Microchip datasheet to confirm it denotes the correct packaging or material specification variant. Confirm RoHS compliance status directly with the manufacturer as regulatory requirements may vary by production batch. Ensure the stud mount interface matches the thermal management design of the target application before finalizing procurement.

Single Diodes Selection Notes

Select this component when a standard recovery time is sufficient for the switching frequency and high current capacity is required. The DO-205AA package is suitable for chassis mounting where space allows for stud-based installation. Evaluate the thermal resistance characteristics to ensure the heatsink design can maintain the junction temperature within the specified +200 °C limit under continuous load conditions.

Single Diodes Part Context

The S4220F belongs to the family of general-purpose silicon rectifiers from Microchip Technology. It is part of a series offering various voltage and current ratings for industrial power conversion. The DO-205AA package is a standardized form factor for high-power discrete semiconductors, facilitating integration into larger power modules and assemblies.

Single Diodes Replacement Considerations

Consult the official Microchip replacement guide for verified equivalents. Generic substitutes must match the 200 V reverse voltage, 125 A forward current, and DO-205AA package dimensions to ensure compatibility.
